CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of U.S. application Ser. No. 16/285,389 filed on Feb. 26, 2019, and claims priority to U.S. Provisional Application Ser. No. 62/639,033 filed on Mar. 6, 2018, the contents of which are incorporated fully herein by reference.

TECHNICAL FIELD

The present subject matter relates to drone communication and, more specifically, to systems and methods of pairing drones in order to facilitate communication with one other.

BACKGROUND

Unmanned aerial vehicles (UAV), commonly known as drones, are aircraft without a human pilot aboard. Conventionally, upon powering on a drone, the drone seeks to establish communication with a controller (e.g., of a user device or another drone). Upon establishing communication, the drone waits to receive pairing data from the controller. The pairing data may be a password sent in a secured link to the drone.

Pairing of multiple drones enables communication between the drones and is useful for coordination of flight patterns desired by drone operators. When there are multiple drones in close proximity, however, it may be difficult to pair the drones as desired by the drone operators.

DETAILED DESCRIPTION

In the following description, numerous specific details are set forth by way of examples in order to provide a thorough understanding of the relevant teachings. How to practice the present teachings, however, should be apparent to those skilled in the art without the need for such details. In other instances, well-known methods, procedures, components, and circuitry are described at a relatively high-level, without detail, in order to avoid unnecessarily obscuring aspects of the present teachings.

In an example, a system includes at least two drones, each of which includes an accelerometer, a processor, and a memory including programming accessible to the processor. Execution of the programing by the processor of a respective one of the at least two drones configures the respective drone to perform functions, including functions to enter a drone pairing mode. Execution of the programming additionally configures the respective drone to determine a first acceleration parameter related to physical contact between the respective drone and another of the at least two drones and to receive a second acceleration parameter from the other of the at least two drones. Execution of the programming further configures the drone to compare the first acceleration parameter of the drone and the second acceleration parameter of the other of the at least two drones to identify a match and pair the drone and the other of the at least two drones in response to the identified match between the compared acceleration parameters of the drone and the other of the at least two drones.

FIG. 1 is block diagram of an example system 100 including a plurality of drones 102 a-102 n. Each of the drones 102 a-102 n includes a respective processor 104 a-104 n, which includes a respective memory 106 a-106 n. In the example illustrated in FIG. 1, each of the drones 102 a-102 n support their respective processors 104 a-104 n including their respective memories 106 a-106 n. Alternatively, each of the processors 104 a-104 n and/or their respective memories 106 a-106 n may be separate components in the system 100. One of skill in the art will understand suitable drones, processors, and memory from the description herein.

Each of the illustrated drones 102 a-102 n include a corresponding accelerometer 108 a-108 n, which measures acceleration parameter of the corresponding drone. Some examples of the acceleration parameter include, but are not limited to, one or more of acceleration, direction of movement, position and/or orientation. In one example, each of the memories 106 a-106 n may store instructions for execution by the corresponding processors 104 a-104 n to utilize their respective drones' 102 a-102 n to perform various functions described herein.

FIG. 2 is flow chart 200 illustrating an example method for pairing two drones. In one example, the system 100 of FIG. 1 implements the steps of the flow chart 200. One of skill in the art will understand other suitable components for implementing the method of flow chart 200 from the description herein.

At block 202, configure each of a first drone and a second drone in a drone-pairing mode. In one example, a first drone 102 a and a second drone 102 b enter into a drone pairing mode when they are powered on, as shown in FIG. 3A. Entering the drone pairing mode may additionally be conditioned upon the drones detecting they are within a pre-defined pairing distance of one another (e.g., within a few meters). The pre-defined pairing distance may be a predefined value stored in a memory 106 a and 106 b of the corresponding first and second drones 102 a and 102 b. In other examples, the drones may enter a drone pairing mode in response to being shaken or colliding with another drone or object (e.g., as determined by processor 104 based on input from accelerometer 108), in response to the processor detecting a press of a button (not shown), and/or in response to a signal from the user device 110. Other techniques for entering a drone pairing mode will be understood by one of skill in the art from the description herein.

At block 204, establish physical contact between the first drone and the second drone while in the drone pairing mode. The physical contact may be a momentary contact (e.g., a tap or a bump or a prolonged contact (e.g., for a few seconds or longer as the drones are moved in tandem in a pre-defined, random, or pseudo random pattern). The drones may include a platform and/or connector (not shown) for facilitating desired physical contact between the drones. Additionally, the drones may include a switch such as a proximity switch for establishing when the drones are in physical contact with one another.

At block 206, determine an acceleration parameter for each of the first drone and the second drone related to the physical contact between the first drone and the second drone. In an example, a first accelerometer 108 a determines a first acceleration parameter of the first drone 102 a. Some examples of the first acceleration parameter include a rate of change of velocity over time, position and orientation of the first drone 102 a. Similarly, a second accelerometer 108 b determines a second acceleration parameter of the second drone 102 b. Each drone 102 may store an output signal from its respective accelerometer 108 in the memory 106 as the respective acceleration parameter. Additionally, each drone 102 may periodically transmit its stored output signal (via a transceiver; not shown) for reception by other drones (via their transceivers; not shown) in the system 100.

At block 208, compare the acceleration parameter of the first drone with the acceleration parameter of the second drone to identify a match. In one example, the first processor 104 a of the first drone 102 a receives the second acceleration parameter of the second drone 102 b and compares the first acceleration parameter of the first drone 102 a with the received second acceleration parameter of the second drone 102 b. The drones may identify a match if at least a portion of acceleration parameters (e.g., approximately a second or more) are substantially identical (indicative of movement during prolonged contact) or are substantially identical in magnitude, but opposite in direction (indicative of a bump or tap). The longer the portion of acceleration parameters required for a match, the higher the likelihood of an accurate match.

In accordance with the prolonged contact example, the first processor 104 a identifies the match when the first acceleration parameter of the first drone 102 a includes a portion that is equal in magnitude and direction to a portion of the second acceleration parameter of the second drone 102 b as illustrated in FIG. 3B. Likewise, the second drone 104 b identifies the match when the second acceleration parameter of the second drone 102 b includes a portion that is equal in magnitude and direction to a portion of the first acceleration parameter of the first drone 102 a.

In accordance with the momentary contact example, the first processor 104 a identifies the match when a portion the first acceleration parameter of the first drone 102 a has the same magnitude but is in an opposite direction to the second acceleration parameter of the second drone 102 b as illustrated in FIG. 3C. Likewise, the second drone 102 b identifies the match when a portion the second acceleration parameter of the second drone 102 b has the same magnitude but is in an opposite direction to the first acceleration parameter of the first drone 102 a.

At block 210, pair the first drone and the second drone in response to the identified match between the acceleration parameters of the first and the second drones. In one example, the first drone 102 a pairs with the second drone 102 b such that the first drone and the second drones 102 a and 102 b are aware of each other's presence and are in communication with each other. For example, each of the first and the second paired drones 102 a and 102 b may communicate their pairing data with each other. The pairing data may include, but is not limited to, identification information unique to the drone, e.g., a serial number or other designated unique identifier. In one example, the first drone 102 a stores the pairing data of the second drone 102 b in its memory 106 a and the second drone 102 b stores the pairing data of the first drone 102 a in its memory 102 b. The first and the second drones 102 a and 102 b may utilize the pairing data to identify communications originating from each other.

At block 212, assign a precedence number to each of the first and the second drones to determine an order of precedence between the first drone and the second drone. In one example, the first and the second drones 102 a and 102 b respectively self-assign a number to determine an order of precedence. In another example, each of the first and the second drones 102 a and 102 b respectively randomly assigns precedence numbers to each other. In one example, a pre-assigned parameter is stored in the first and/or second memories 106 a or 106 b respectively. In one example, the one of the first or the second processors 104 or 104 b utilizes the pre-assigned parameter to determine an order of precedence and accordingly assigns the number to each of the first or the second drones 102 a and 102 b respectively. The parameter may include but is not limited to a serial number assigned to the first and the second drones and/or timing clocks of the first and the second drones. In one example, the numbers assigned to the first and the second drones 102 a and 102 b respectively are stored in their respective memories 106 a and 106 b.

At block 214, designate a group including the two or more paired drones with their corresponding assigned numbers. FIG. 3D illustrates a group 300 including the first and the second drones 102 a and 102 b respectively with their corresponding assigned numbers 1 and 2. In one example, the user device 110 designates the first and the second paired drones 102 a and 102 b respectively in the group to complete a task specific to the group. For example, the task of a first group (e.g., of heavier drones) may include projecting stable background images onto a surface of an object, while the task of a second group (e.g., of more nimble drones) may be projecting a foreground image(s). In one example, the system generates multiple groups including two or more drones.

In one example, upon designating the group including the first and the second paired drones, the system determines an additional drone to pair with the first and second paired drones. For example, a third drone 102 c to pair with the first drone and second drone 102 a and 102 b in the group 1. In one example, the system performs the steps in the blocks 202-210 of the flow chart 200 for the third drone to pair with either the first drone or the second drone that is part of pre-existing group 300. FIG. 3E illustrates the pairing of third drone 102 c with either the first drone 102 a or the second drone to add the third drone to the group 300. In one example, the system assigns the third drone with a number followed by the number assigned to the second drone in the group in the order of precedence. For example, the third drone 102 c is assigned the number 3 in the group 300 as illustrated in FIG. 3F.

Referring back to FIG. 1, in one example, the system 100 also includes a user device 110, which communicates with each of the drones' 102 a-102 n with a network 120 such as an intranet and/or the Internet. The network 120 may include a wireless communication network such as a radio frequency communication, light communication, satellite communications etc. In one example, the user device 110 is a mobile user device such as a smartphone, smart eyewear, a laptop, a personal computer (PC), a desktop, or other smart device capable of triggering the first and the second drones to enter a pairing mode and assigning an order of precedence to each of the first and the second drones (e.g., alone or with assistance of a remote computing device).

FIG. 4 is flow chart 400 illustrating an example method for pairing two drones utilizing a user device. In one example, the system 100 of FIG. 1 implements the steps of the flow chart 400 utilizing the user device 110 of FIG. 1. One of skill in the art will understand other suitable components for implementing the method of flow chart 400 from the description herein.

At block 402, determine that at least two drones are in a drone-pairing mode. In one example, a first drone 102 a and a second drone 102 b enter into a drone pairing mode when they are powered on. Entering the drone pairing mode may additionally be conditioned upon the drones detecting they are within a pre-defined pairing distance of one another (e.g., within a few meters). The first and second drones 102 a and 102 b may communicate that they are in a drone pairing mode to the user device 110. In other examples, the drones may enter a drone pairing mode and communicate that they are in a drone pairing mode to user device 110 in response to being shaken or colliding with another drone or object (e.g., as determined by processor 104 based on input from accelerometer 108), in response to the processor detecting a press of a button (not shown), and/or in response to a signal from the user device 110. Other techniques for entering a drone pairing mode will be understood by one of skill in the art from the description herein.

At block 404, each of at least two drones receive a machine-readable code from a user device. In one example, each of the first and second drones 102 a and 102 b respectively receives a machine-readable code from an application (not shown) of the user device 110 via the network 120. The machine-readable code may be a visual identifier such as a quick response (QR) code received by the processor 104 of a drone (e.g., via an imager of the drone; not shown). The processor 104 a of the first drone 102 a may receive the machine-readable code and the processor 104 b of the second drone 102 b may receive the same machine-readable code.

At block 406, upon receipt of the machine-readable code, trigger each of the at least two drones to pair with each other. In one example, each of the first and the second drones 102 a and 102 b respectively pair with one another based on the information received from the machine-readable code. For example, the processor 104 a of the first drone 102 a and the processor 104 b of the second drone 102 b may communicate the received machine-readable code with each other, which triggers each of the first and the second drone 102 a and 102 b to pair with each other.

At block 408, assign numbers to each of the at least two drones based on number of taps received from the user device to determine an order of precedence between the at least two drones. In one example, the user device 110 is used to assign precedence based on taps to each drone. For example, a user may tap the user device 110 one time on the first drone 102 a to assign a first priority and two times on the second drone 102 b to assign a second priority. The processor 104 may identify the number of taps based on input from its respective accelerometer 108 and may interpret the priority based on the number of taps and interpretation instructions stored in memory.

Aspects of the methods for drone pairing, as outlined above, may be embodied in programming in general purpose computer hardware platforms 500 and 600 (such as described above with respect to FIGS. 5 and 6), e.g., in the form of software, firmware, or microcode executable by a networked computer system such as a server or gateway, and/or a programmable nodal device.

In one example, program aspects of the technology are “products” or “articles of manufacture” typically in the form of executable code and/or associated data that is carried on or embodied in a type of machine-readable medium. “Storage” type media include any or all of the tangible memory of the computers, processors or the like, or associated modules thereof, such as various semiconductor memories, tape drives, disk drives and the like, which may provide non-transitory storage at any time for the software programming. All or portions of the software may communicate through the Internet or various other telecommunication networks. Such communications, for example, may enable loading of the software, from one computer or processor (e.g., CPU 502 and CPU 602 of FIGS. 5 and 6 respectively) into another, for example, from a processor 104 a-104 n of the system 100 to a computer or software of another system (not shown). Thus, another type of media that may bear the software elements includes optical, electrical and electromagnetic waves, such as used across physical communication interface(s) 504 and 604 of FIGS. 5 and 6 respectively, between local devices, through wired and optical landline networks and over various air-links. The physical elements that carry such waves, such as wired or wireless links, optical links or the like, also may be considered as media bearing the software. As used herein, unless restricted to one or more of “non-transitory,” “tangible” or “storage” media, terms such as computer or machine “readable medium” refer to any medium that participates in providing instructions to a processor for execution.

Hence, a machine-readable medium may take many forms, including but not limited to, a tangible storage medium, a carrier wave medium or physical transmission medium. Non-transitory storage media include, for example, optical or magnetic disks, such as any of the storage devices in any computer(s) or the like. It may also include storage media such as dynamic memory, for example, the main memory of a machine or computer platform. Tangible transmission media include coaxial cables; copper wire and fiber optics, including the wires that include a bus (e.g., 506 and 606 of FIGS. 5 and 6 respectively) within a computer system that communicates to other components of the computer system via an input/output (I/O) 508 and 608 of FIGS. 5 and 6 respectively. Carrier-wave transmission media can take the form of electric or electromagnetic signals, or acoustic or light waves such as those generated during radio frequency (RF) and light-based data communications. In one example, as shown in FIG. 5, the computer system includes a video display unit 510, (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)), an alphanumeric input device 512 (e.g., a keyboard), a cursor control device 514 (e.g., a mouse), each of which communicate via the I/O 508.

Common forms of computer-readable media therefore include for example: a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any other optical medium, punch cards paper tape, any other physical storage medium with patterns of holes, a RAM (e.g. 516 and 616 of FIGS. 5 and 6 respectively), a ROM (e.g. 518 and 618 of FIGS. 5 and 6 respectively), hard disk drive (e.g. 520 and 620 of FIGS. 5 and 6 respectively) a PROM and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave transporting data or instructions, cables or links transporting such a carrier wave, or any other medium from which a computer can read programming code and/or data. Many of these forms of computer readable media may be involved in carrying one or more sequences of one or more instructions to a processor for execution.

Program instructions may include a software or firmware implementation encoded in any desired language. Programming instructions, when embodied in machine-readable medium accessible to a processor of a computer system or device, render computer system or device into a customized special-purpose machine to perform the operations specified in the program performed by processor 104 a-104 n of the system 100.
